So does anyone have a definate answer and or parts replaced to the mystical "rear air coming on full blast after turning off vehicle myth" I just picked up a used 2007 CX-9 and the day I brought it home (Friday) I turned it off and the rear air blasted on itself, I came back to leave on the car about 15 minutes later and it was off....
So does anyone have a definate answer? Any Mazda techs out there that have encountered or fixed this issue?
I am out of warranty so if it just a switch or a relay a part number and location is all I need to purchase it and install it myself. Thanks!

Check out the "new member thread" he is a Mazda tech. I asked him, see his reply below
If you're referring to the blower motor (fan for air coming out of the dash vents--front blower, or fan for air coming out of the vents on back of center console--rear blower), TSB 07-008/09 addresses that issue. If you haven't driven 36,000 miles yet, take your vehicle into your nearest dealer and mention the TSB number listed above.
However if you're referring to a radiator/condenser fan under the hood, that may run to cool the motor when you turn the car off.

Thanks! This is super helpful. My dealer tech seemed baffled since the problem wouldn't happen when the car was with them. Now I have something to go back with since I am still in warranty. Really appreciate your help.

Dealer has access to electronic versions of TSBs.
Last time I printed out TSB when I visited my dealer, the service advisor returned it to me and said, "We can find it on our computer."

My CX9 is out of warranty so I asked my buddy that works at Riverside Mazda to hook me up with a copy of TSB 07-008/09. I read through it and was very simple and straight forward. I bought the relay that the TSB said to replace (part# G115-67-730) replaced it (under hood relay box closest to the driver's side fender) and up to right now no more occurences.
#25 of 79 2007 CX9 Rear Air Stays On
Jan 11, 2009 (3:15 pm)
I think this car has an electrical gremlin. The trip odometers reset themselves regularly and the dash dim light (for when the headlights come on) also resets itself. Now, within the last two months, when you turn off the car the rear air comes on. The first time my wife just turned the car on and back off. This would fix the problem. Today when it happened, I turned the car back on and turned off all air controls. I then turned the car off and the rear vents were still blowing. I turned the car back on and off again. The rear air remained on for over six minutes. I turned the car on and off again at this point and it finally turned off. This has happened four times in two months.
Has anyone else had this problem or the odometer ones? I took it to the dealer three months ago when the check engine light came on and the car started to run real rough and then would die. Took them three days to figure out a vaccuum line had broken near the firewall. They never could figure why the meters reset.

Did you install accessories recently?
It seems like some electrical short exists in your vehicle (that causes improper grounding).
You need to have it checked out by your dealers before the OE warranty expires.

we are NOT car people. have a 2007 Mazda cx9. when you turn the key off and remove the key the air conditioning stays on and you can still make the windows go up and down. the A/C turns off after about 30 seconds to a minute. is this some new thing or is our electrical system messed up? thanks in advance for the help.
